Patent JP-H0723533-A (JP)
Title: Charger
Inventor: SOGA IZURU
IPC: H02J7/10
Filed: 1993-06-30
Abstract: PURPOSE:To prolong the service life of a Ni-Ca battery by starting the charging operation only when the voltage of the Ni-Ca battery drops below a predeter mined level through discharge thereby preventing the memoryode effect. CONSTITUTION:A charging circuit 7 feeds power to a Ni-Cd battery 2 under control of a CPU 9 thus conducting the boosting charge. After the battery voltage reaches a peak value Vp, a decision is made whether the voltage has dropped by DELTAV and if the voltage has dropped by DELTAV, the CPU 9 controls the charging circuit 7 to interrupt the charging power supply to the Ni-Cd battery 2. Subsequently, the CPU 9 sustains interruption of the charging power supply until the battery 2 voltage drops down to a predetermined charge restart voltage Va through discharge and then starts recharging operation. This procedure prevents memoryode effect and prolongs the service life of battery.

Title: Electrode for electric discharge machining
Inventor: OKUNO MICHIO
IPC: H05B7/08
Filed: 1987-07-27
Abstract: PURPOSE:To enable the development of an electrode having a small value of a machining removal amount/electrode consumption for copper and copper alloy electrodes by using an electric discharge machining electrode comprising a stranded plurality of copper and copper alloy wires or hollow wires and with the external surface thereof subjected to a compression molding process. CONSTITUTION:A plurality of wires or hollow wires comprising pure copper and brass or a copper alloy and the like added with brass, FAl, Mg, Si, Ti, Sn and the like are stranded and then the external surface of a strand 1 is compression molded to such a circular form as having a smaller diameter than the diameter 2 of the original strand via die drawing, bore type rolling, swaging and other processes. In this case, the strand is compression molded to a circular form, because it is impossible to unify the outer diameter of the strand in a length-wise direction simply by stranding round wires and improve machining accuracy. An electrode of uniform outer diameter is available via compression molding, thereby enabling the reduction of a value of a machining removal amount (mg)/electrode consumption (mg).

Title: Image formation device
Inventor: MIZUMOTO TERUYUKI
IPC: B41J31/00
Filed: 1990-07-16
Abstract: PURPOSE:To make it easy to print in color by making a photoconductive powder ink conductive by a light irradiation so as to replenish the ink, melting and solidifying the replenished powder ink so as to reproduce an ink sheet. CONSTITUTION:An untransferred part 6 having the same composition as an ink layer 2 absorbs and scatters an exposed light and an untransferred ink layer becomes conductive. However, a powder ink 7 itself holds an initial electric charge as it is since it does not receive a light irradiation. The powder ink 7 contacted with the untransferred part 6 is conveyed on a conductive sleeve 10 due to an electrostatic force by applying an apply bias so as to make a sleeve side plus. Thus, only a transferred section of the photoconductive ink layer 2 can be replenished with the powder ink 7. Next, the powder ink 7 is solidified on an ink sheet of the photoconductive ink by solidifying means 14 such as heat roller or heat pressure roller, so that an ink layer of the ink sheet is reproduced and taken up to a cartridge.

CONSTITUTION:When the demand of product oxygen gas is reduced, a pressure in a product oxygen supplying conduit 11 is increased in accordance with the reduction of said demand whereby the pressure regulator 36a of a liquefied oxygen producing means is operated to choke a control valve 36b in accordance with the increasing amount of the pressure. Accordingly, the amount of introduction of the liquefied oxygen from a liquefied oxygen storage tank 13 is reduced and the evaporating amount of a sub heat exchanger 14 is reduced whereby the amount of product oxygen gas, supplied to the demanding source, can be reduced. In this case, a nitrogen gas amount control means is operated to increase the introducing amount of nitrogen gas into a nitrogen gas indroducing tube 19 and maintain the condition of an auxiliary fractionating tower 6 in constant.

Title: Method for preparing analytical curve in analyzer
Inventor: ARITA YOSHIHIKO
IPC: G01N21/61
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To obtain a stable concentration indication without large fluctuation of origin indication when an analytical curve is switched from a positive concentration area to a negative concentration area by setting a differential coefficient at the origin of a function as the gradient of the analytical curve in the negative concentration area. SOLUTION: The differential coefficient at an origin of an analytical curve in a positive concentration area expressed by a function of a detection signal from a detector is made the gradient of the analytical curve in a negative concentration area. That is, when a curve A expressed by a function of F(x)=axn+bxn-1+...+cx+d is used for the analytical curve in the positive concentration area, a differential coefficient F(0)=c(c>0) in the case of x=0 is obtained, and this value is made the gradient of the analytical curve in the negative concentration area. A straight line C expressed by G(x)=cx is therefore used.  The measured concentration value in the negative concentration area is therefore the smooth continuous value without abrupt fluctuation compared to a concentional method so as to suppress the abrupt fluctuation of concentration indication at a switchover point between the analytical curve A in the positive concentration area and the analytical curve C in the negative concentration area.

Title: Production of preform for optical fiber
Inventor: ITO YOSHITAKA
IPC: C03B8/02
Filed: 1986-08-11
Abstract: PURPOSE:To obtain a preform for optical fibers capable of readily giving a steep refractive index distribution in a short time, by diffusing a dopant solution from the inner wall surface side of a tube to the radial direction while rotating a tubular silica porous body, drying and sintering the porous body. CONSTITUTION:A dopant solution is diffused in a tubular silica porous body, dried and sintered to produce a preform for optical fibers. In the process, the dopant is diffused from the inner wall surface side to the radial outward direction while rotating the preform for the optical fibers with the symmetry axis of rotation as the center. A tubular porous body produced by a sol-gel method is preferred for the tubular silica porous body used. The dopant solution may be directly diffused in the tubular silica porous body in a dry state, but the diffusion is preferably carried out after certain heat treatment from aspects of optimizing microstructure for high strengthening and diffusion behavior of the porous body. The speed of the above-mentioned rotation may be >=1G at the minimum expressed in terms of centrifugal force acting on the inner wall surface side of the tube, but is preferably about >=5G for practical use.
